| Abstract: |
| Iron-based materials can reduce effective state heavy metals proportion and heavy metals bioavailability in soil, and control heavy metals toxicity. There are advantages of wide source, low production cost and good stable effect. Operation mechanism of iron-based materials during soil heavy metals remediation such as adsorption, precipitation, reduction, oxidation, as well as influencing factors such as soil moisture, pH value, organic content and ion competition were summarized and discussed though referring to domestic and overseas literatures. Potentiality and future research direction of iron-based materials remediation in heavy metal contaminated soil were expected. |
